Maximillian's Plan
Previously, Emperor Evergreen was intent on not finding and rescuing Maximillian since no one would believe this man was still alive. The opposite of this, the goal of the one behind the Blood Triangle Pirates was to obtain the body of this Demigod and use it to his advantage.
Within the Spiritual Church, specifically in the Emperor Evergreen faction, there was a member with an innate ability that allowed her to use corpses to create warriors almost as strong as the owners of those corpses.
Maximillian was a monster who had reached near peak cultivation and had an ability everyone thought would preserve his body. So his body was valuable and, if found, could become a great weapon for the emperor of this state.
Norman knew this, but upon finding out that this man was alive, he cleverly put those plans aside and pretended that his group's goal was to free him from that sarcophagus.
